[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] refer to Figure 1 and 2 , Figure 1 A cleaning system 101 is disclosed, which includes a surface cleaning device 100 and a base station 200 for docking the surface cleaning device 100. Figure 2 A schematic diagram of a robotic vacuum cleaner is disclosed. The surface cleaning device 100 generally includes a main unit 10 and a cleaning head 20 connected to the main unit 10. When the surface cleaning device 100 is a vertical cleaning device, the main unit 10 and the cleaning head 20 can pivot relative to each other. When the surface cleaning device 100 is an autonomous cleaning device such as a robotic vacuum cleaner, the main unit 10 and the cleaning head 20 can be integrated together. The main unit 10 generally has a defined receiving space, within which components such as a wastewater tank, a suction motor, and a clean water tank can be placed. The surface cleaning device 100 generally includes a dirt recovery system and / or a cleaning fluid supply system. The dirt recovery system includes a suction motor that generates suction airflow and a recovery tank for collecting dirt. The cleaning fluid supply system includes a cleaning fluid tank and supply pipelines. It is used to directly or indirectly supply cleaning fluid to the surface 102 to be cleaned. Directly supplying cleaning fluid to the surface to be cleaned means that the cleaning fluid can be directly sprayed onto the surface; indirectly supplying cleaning fluid to the surface to be cleaned means that the cleaning fluid can be sprayed onto a roller brush, and the cleaning fluid is carried to the surface by the rotation of the roller brush. (Reference) Figure 3-18The following section mainly describes the detailed structure of the cleaning head 20. The cleaning head 20 generally includes an upper housing 28 and a lower housing 27. The upper housing 28 and lower housing 27 define an installation space. A motor or other functional components can be installed within this installation space. Since the surface cleaning device 100 is a device well-known to those skilled in the art, its working principle will not be detailed here. (Reference) Figure 3-9 The structure of the cleaning head 20 is described in detail below. The cleaning head 20 defines a suction chamber, within which a roller brush 21 is installed. The roller brush 21 rotates at high speed, lifting up dirt from the surface 102 to be cleaned, which is then collected into a collection bin. To improve the cleaning ability for sewage and other dirt, a first scraper 22 is provided at the edge of the suction chamber. The first scraper 22 is interference-fitted with the surface 102 to be cleaned, used to scrape off at least part of the dirt, while improving the sealing of the suction chamber (i.e., suction capacity). To improve the ability to clean stubborn debris, the cleaning head 20 also includes a second scraper 23 located behind the first scraper 22 or the roller brush 21. The second scraper 23 is preferably located behind the first scraper 22. The hardness of the second scraper 23 is greater than that of the first scraper 22. The first scraper 22 can be made of a relatively soft rubber material, which can deform upon contact with a hard surface to better conform to the surface and scrape away dirt and water stains. The second scraper 23 can also be made of rubber, but with greater hardness. It essentially does not deform upon contact with a hard surface, allowing it to effectively scrape stubborn stains. Alternatively, the second scraper 23 can be made of other hard materials. The second scraper 23 can be curved along its length, or it can be other shapes. When the second scraper 23 is in operation, its working surface or end should ideally be at an angle to the surface 102 to avoid scratching it. This angle can be between 1° and 40° (refer to the angle at which a user scrapes dirt with a small shovel). This effectively prevents scratching the floor. The outermost part of the second scraper 23 (i.e., the suspended end) can be rounded to prevent it from scratching other objects when extended. Due to the high hardness of the second scraper 23, prolonged use may damage the surface 102. The second scraper 23 can move between a first position and a second position. In the first position (refer to...) Figure 4 and 6 The second scraper 23 contacts the surface 102 to be cleaned to scrape away at least part of the dirt on the surface 102 as the cleaning head 20 moves. In the second position (refer to...) Figure 3 and 5The second scraper 23 is positioned away from the surface 102 to be cleaned. To enable the second scraper 23 to move between the first and second positions, the surface cleaning device 100 also includes a driver 24 for driving the second scraper 23. When there is stubborn debris on the floor that the roller brush 21 cannot remove, the driver 24 can move the second scraper 23 to the first position. Since the second scraper 23 is much harder than the first scraper 22, it can scrape the surface 102 to remove stubborn stains. Furthermore, the outermost (suspended end) of the second scraper 23 can be fitted with an anti-collision structure and / or a wiping element to simultaneously wipe baseboards, corners, and other side structures.

[0048] refer to Figure 4 The projection area of ​​the cleaning head 20 relative to the surface 102 to be cleaned along the vertical direction is designated as the first region 31. When the second scraper 23 is in the first position, the contact area between the second scraper 23 and the surface 102 to be cleaned is designated as the second region 32, with at least a portion of the second region 32 located outside the first region 31. When at least a portion of the second region 32 is outside the first region 31, it can be understood that a portion of the second scraper 23 is located outside the cleaning head 20. This allows the user to more easily align the second scraper 23 with the dirt and to more easily see whether the dirt has been effectively removed during the scraping process. The second region 32 can be located to the side of the first region 31 or behind the first region 31.

[0049] refer to Figure 4-9 In one embodiment, when the second scraper 23 is in the first position, at least a portion of the second scraper 23 protrudes from the sidewall 30 of the cleaning head 20, i.e., the second region 32 is located on the side of the first region 31. To ensure that the second scraper 23 does not contact the surface 102 to be cleaned in the second position, and that it contacts the surface 102 after extending from the side of the cleaning head 20 to the first position, the second scraper 23 moves in an inclined direction relative to the surface 102 to be cleaned at a first angle, where the first angle is greater than 0° and less than 30°. The movement of the second scraper 23 in an inclined direction relative to the surface 102 to be cleaned at a first angle can be understood as the second scraper 23 moving simultaneously along a first direction and a second direction, where the first direction is a downward vertical direction and the second direction is a horizontal direction perpendicular to the first direction. This is equivalent to the second scraper 23 moving obliquely downwards, but the working surface of the second scraper 23 remains parallel to the surface 102 to be cleaned. The second direction can be parallel to the axis of the roller brush 21, or it can be at a certain angle to the axis of the roller brush 21. That is, after the second scraper 23 extends, it can be perpendicular to the side wall 30 of the roller brush 21 (see reference). Figure 4 It can also be at a certain angle to the side wall 30 of the roller brush 21 (see reference). Figure 12That is, the second scraper 23 can be tilted forward or backward relative to the side wall 30.

[0050] The actuator 24 can be a manual actuator 24 or an automatic actuator 24. When the actuator 24 is a manual actuator 24 (not shown in the figure), the actuator 24 includes a driving member and a transmission member that drives the driving member and the second scraper 23. The cleaning head 20 includes an upper housing 28 and a lower housing 27. The driving member is disposed on the cleaning head 20 and protrudes from the upper housing 28 so that it can be operated by the user. The user can manipulate the driving member, which drives the second scraper 23 to move relative to the lower housing 27 via the transmission member, raising or lowering the second scraper 23 to move away from or to contact the surface 102 to be cleaned. In another embodiment, the driving member is disposed on the handle of the main unit 10, and the transmission member drives the driving member and the second scraper 23. The user controls the movement of the second scraper 23 between a first position and a second position through the driving member located on the handle.

[0051] refer to Figure 8 and 9 14-18, When the actuator 24 is an automatic actuator 24, the actuator 24 includes a drive motor 241 and a controller for controlling the drive motor 241. The controller is configured to drive the drive motor 241 according to a signal to control the movement of the second scraper 23 between a first position and a second position. Specific control components are not detailed here. The handle may be equipped with a control button for issuing control signals. The controller controls the movement of the second scraper 23 between the first and second positions according to the signals issued by the control button. Specifically, the actuator 24 also includes a transmission structure 242, which includes a drive gear 243 mounted on the drive shaft of the drive motor 241, a transmission rack 244 meshing with the drive gear 243, and a mounting bracket 245 for mounting the second scraper 23. The transmission rack 244 is fixedly mounted on the mounting bracket 245. The second scraper 23 can be fixed to the mounting bracket by rubber coating, or by bolts, snap-fitting, welding, etc. The second scraper 23 is substantially parallel to the surface 102 to be cleaned, and the extension direction of the transmission rack 244 is set at a first angle relative to the second scraper 23. In this way, during the movement of the second scraper 23, its working surface is kept substantially parallel to the surface 102 to be cleaned, and the second scraper 23 achieves oblique movement through the inclined transmission rack 244.

[0052] refer to Figure 14-18In order to enable the second scraper 23 to switch smoothly between the first position and the second position, a first guide structure 25 is provided on the mounting bracket 245, and a second guide structure 26 corresponding to the first guide structure 25 is provided on the cleaning head 20. The first guide structure 25 and the second guide structure 26 cooperate to guide the second scraper 23 to move in an inclined direction relative to the surface 102 to be cleaned at a first angle.

[0053] refer to Figure 5 , 14 15. The cleaning head 20 includes an upper housing 28 and a lower housing 27. When the second scraper 23 is in the second position, the second scraper 23 moves into the receiving cavity defined by the lower housing 27. That is, when the second scraper 23 is in the second position, the bottom of the second scraper 23 can be completely retracted into the lower housing 27. Retracting the second scraper 23 completely into the receiving cavity can prevent damage to the ground due to unevenness.

[0054] refer to Figure 10 and 11 The cleaning head 20 also includes a first roller assembly 41 disposed behind the first scraper 22 and a second roller assembly 42 disposed at the rear end of the cleaning head 20. The first roller assembly 41 and the second roller assembly 42 together support the cleaning head 20. The second scraper 23 is disposed between the first roller assembly 41 and the second roller assembly 42. When the second scraper 23 is in the first position, the lowermost end of the second scraper 23 is lower than the plane defined by the first roller assembly 41 and the second roller assembly 42.

[0055] Continue to refer to Figure 10 and 11 To improve the cleaning effect of the second scraper 23 on the ground, the first roller assembly 41 separates from the hard ground after the second scraper 23 contacts the hard ground. At this time, the first roller assembly 41 does not contact the ground, and the second scraper 23 and the second roller assembly 42 jointly support the cleaning head 20. The second scraper 23 is subjected to greater force, and the cleaning effect is also better.

[0056] refer to Figure 12 and 13 The cleaning head 20 may include two second scrapers 23 along the axial direction of the roller brush 21, one of which extends from one side of the cleaning head 20 and the other extends from the other side of the cleaning head 20 (see reference). Figure 13 Furthermore, multiple second scraper strips 23 can be installed on each side of the cleaning process, and the arrangement of the multiple second scraper strips 23 can also be adjusted according to actual needs (see reference). Figure 12 ).

[0057] Based on the above embodiments, in order to achieve self-cleaning of the second scraper 23, when the second scraper 23 is in the second position, the second scraper 23 can be in interference contact with the roller brush 21. In this way, the second scraper 23 can be self-cleaned both during the operation of the surface cleaning equipment 100 and during its self-cleaning process. A third scraper can also be provided on the cleaning head, generally positioned behind the roller brush 21 and above the first scraper 22. The third scraper can always be in interference fit with the roller brush. When the second scraper 23 is in the second position, the second scraper 23 can be positioned adjacent to the third scraper.

[0058] Based on the above embodiment, the second scraper 23 is configured to rotate or move relative to its own axis when in the second position, and after rotation or movement, the second scraper 23 can make interference contact with the roller brush 21. That is, in the second position, the second scraper 23 is neither in contact with the surface 102 to be cleaned nor with the roller brush 21. When self-cleaning is required, the second scraper 23 can be rotated or moved to make it contact the roller brush 21. The roller brush 21 can remove dirt from the second scraper 23. When self-cleaning of the second scraper 23 is required, the second scraper 23 can be rotated or moved relative to its own axis by the controller.

[0059] This application also discloses a cleaning system 101, which further includes a surface cleaning device 100 and a base station 200 in any of the above embodiments. The base station 200 is used to dock with the surface cleaning device 100 and defines a cleaning chamber for accommodating at least a portion of the second scraper 23.

[0060] The second scraper 23 is configured to be in a second position (see reference) Figure 5 ) and the third position (reference) Figure 7 The second scraper 23 moves between the second and third positions. When the second scraper 23 is in the third position, at least part of the second scraper 23 extends into the cleaning chamber. At this time, the second scraper 23 can be cleaned by the liquid in the cleaning chamber. After cleaning, the second scraper 23 can be controlled to move back to the second position. The controller of the surface cleaning device 100 is also configured to control the second scraper 23 to move from the second position to the third position only when the surface cleaning device 100 is connected to the base station 200. That is, when the surface cleaning device 100 is performing surface cleaning work, it is not allowed to move to the third position to prevent scratching the floor.

[0061] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
